اقرأ أكثرThe amount of waste generated by the wet process is slightly more than the dry process due to more use of leaching. Waste-Water Treatment Practices: Few steps in the manufacture of cement directly produce liquid wastes. In non-leaching plants, contact of raw material or final product with water provides the major source of the waste load.
اقرأ أكثرThe tannery industry is one of the most polluting industries considering the generation of a massive amount of liquid and solid waste [2,3]. The literature indicates that normally only 255 kg of finished leather is produced by processing 1 ton of raw hides, where approximately 75% of the raw material is discarded in the form of collagen and ...
اقرأ أكثرIn this paper a cement-based cementitious system is studied for the stabilization of tannery sludge. Two binders were used as stabilizing matrices: pozzolanic cement alone and a 3:7 cement/blast furnace slag mixture.
اقرأ أكثرThe paper analyses the properties (chemical and mineral composition, microstructure, density, etc.) of recycled tannery sludge (TS) and the possibilities for using it in cement mortar mixture. Mortar specimens containing 3–12% of tannery sludge by weight of cement and 3–9% of tannery sludge by weight of sand were tested. Flowability, density, …

Tanning is the process that converts the protein of the raw hide or skin into a stable material which will not putrefy and is suitable for a wide variety of end applications.
اقرأ أكثرTannery waste (TW) has been the subject of many research work regarding potential applications such as the production of collagen and biochar . This latter product has lately been a fertile area of research as partial substitute for cement replacement in building components.
اقرأ أكثرThe three types of hides and skins most often used in leather manufacture are from cattle, sheep, and pigs. Out of 1000 kg of raw hide, nearly 850 kg is generated as solid wastes in leather processing. Only 150 Kg of the raw material is converted in to leather. A typical tannery generate huge amount of waste: Fleshing: 56-60%
اقرأ أكثرToday, the cement industry provides a significant contribution to the waste management practices of many countries. The responsible use of waste as an alternative fuel to heat cement kilns is lowering the industry's consumption of fossil fuels, which is helping to reduce the environmental footprint of global cement production.
